Lamberton Skerrs Wikipedia
Lamberton Skerrs is the southernmost point on the east coast of Scotland. It was the scene of a building known as the "Smuggler's Bothy" which was built by the famous smuggler John Robertson in about 1760 and stands on the cliffs overlooking the North Sea. He smuggled tea and was in partnership with a Swedish shipping line. The cover for the operation was fishing but the building was actually later used as a fishery cottage. It was eventually destroyed by vandals who set it alight. A rusted net winch and storage caves built into the rocks are all that remains of the fishery.
The East Coast Railway runs right by the location before passing over the border and stopping at Berwick-Upon-Tweed.
